Light-emitting diode chip, display panel, electronic device

A display panel, comprising a backplane and a plurality of LED chips mounted on the backplane, wherein

• each of the plurality of LED chips comprises a first semiconductor layer, a second semiconductor layer, a first electrode electrically connected with the first semiconductor layer, and a second electrode electrically connected with the second semiconductor layer;
• the first electrode is in an annular shape and surrounds the second electrode;
• the first electrode and the second electrode cooperate to define a first channel there between, the first channel being in an annular shape;
• and
• the first electrode defines at least one second channel therein, the at least one second channel extends through an inner side and an outer side of the first electrode and communicates with the first channel.
